Background


Background

I am currently employed as a research associate on the EPSRC funded ACHILLES project with my work primarily focussed on the modelling of the deterioration of geotechnical infrastructure subject to annual weather cycles.

I am a geotechnical engineer with experience in the computer modelling of shallow mining subsidence (as part of my PhD) and I have since undertaken hydrological and mechanical modelling of slopes and slope stability.

During my time at Newcastle University, I have worked as a research assistant on the BIONICS project, In 2011 I undertook a 1 year secondment into the geotechnics group of ARUP's Newcastle office working on slope stability modelling and then worked as an assistant lecturer teaching on both undergraduate and postgraduate modules in geotechnical engineering. From 2013 to 2018 I worked as a research associate on the EPSRC funded iSMART project.

  • CEG8202: Ground Investigation - Design, Principles and Practice
  • CEG8208: Geotechnical Design
Research

Research to date has focussed on applied computational geomechanics to investigate shallow mining subsidence as well as rainfall induced slope instability, using software such as the FDM and FEM codes FLAC 3D and PLAXIS as well as LE codes such as SLOPE.

Currently I am working on the EPSRC funded ACHILLES project with my work primarily focussed on the modelling of the deterioration of geotechnical infrastructure subject to annual weather cycles 

At present I am focussing on modelling work having helped develop the work packages for the Simulation and Modelling theme in phase 2 of the project.

My typical work involves the modelling of the effects of meteorological parameters on pore water pressures in infrastructure slopes and how this in turn affects their stability. This is primarily undertaken with the hydrological code SHETRAN and the geomechanics modelling code FLAC (with the two phase flow add on to allow the modelling of partially saturated flow behaviour).

In the past I worked as a research associate on the ESPRC iSMART project and as a research assistant on the BIONICS project (Biological and engineering impacts of climate on slopes) and was seconded into a consultancy firm where I undertook validation of their finite element software for use in slope stability analysis.
